Abstract

"SINCRONIZAçãO DE TEMPO PARA SISTEMAS MóVEIS". Método de manter a sincronização de tempo de um terminal móvel de uma rede de telecomunicação, o terminal móvel tendo clocks de alta velocidade e de baixa velocidade, em modo de sono profundo, compreendendo: quando o modo de sono profundo é iniciado, faz-se uma medição inicial para estabelecer um relacionamento de freq³ência entre os clocks de alta velocidade e o de baixa velocidade, iniciando-se o modo de sono profundo no qual o clock de alta velocidade é desativado, e atualiza-se a dita correlação com base no tempo de chegada de blocos de radiochamada, cronometrado pelo clock de baixa velocidade."TIME SYNCHRONIZATION FOR MOBILE SYSTEMS". A method of maintaining time synchronization of a mobile terminal of a telecommunication network, the mobile terminal having high speed and low speed clocks in deep sleep mode comprising: when deep sleep mode is initiated, it is performed an initial measurement to establish a frequency relationship between high-speed and low-speed clocks, initiating the deep sleep mode in which the high-speed clock is deactivated, and the time-based correlation is updated radio block arrival time, timed by the low-speed clock.
